A nurse is reviewing the DSM-5 diagnostic criteria for schizophrenia. Which of the following symptoms must be present for a client to be diagnosed with schizophrenia? (Select All that Apply.)

A. Hallucinations. Hallucinations, particularly auditory hallucinations, are one of the core symptoms of schizophrenia. They involve perceiving things that are not present, such as hearing voices. B. Inability to initiate activities. While this may be a feature of schizophrenia, it is not one of the primary diagnostic criteria. This symptom may be related to negative symptoms but is not specifically required for diagnosis. C. Antisocial personality. Antisocial personality disorder is a separate diagnosis and not a symptom of schizophrenia. The presence of antisocial personality traits does not fulfill the criteria for schizophrenia. D. Lack of emotional expression. This symptom, often referred to as flat affect, is considered a negative symptom of schizophrenia and can contribute to the diagnosis, as it indicates diminished emotional responsiveness. E. Disorganized behavior. Disorganized behavior, including disorganized speech and erratic actions, is a key symptom of schizophrenia and is part of the diagnostic criteria. F. Impaired interpersonal relationships. While impaired relationships may result from the symptoms of schizophrenia, this is not a specific criterion for diagnosis. The focus is on the presence of specific symptoms such as hallucinations, disorganized behavior, and negative symptoms like lack of emotional expression.
